4 Claims. (01. 16-163) This invention relates to the hinged mounting ofa sash and the like in a suitable frame for movement in the frame.

The present invention relates to an improved hinge mounting for a sashor like structure in a frame so that the sash can be moved in the frameto open and close the opening provided by the frame. While hinges ofthis general type have been available heretofore, that whichcharacterizes the present invention is extremely simple and rugged,quite inexpensive to manufacture, is easily installed and possesses theadditional that one of the hinge structures can be utilized on eitherside of the sash so that it is unnecessary to make up a right-hand hingeand a left-hand hinge. In addition, the hinge can'be utilized on sash ofeither the easement or awning type.

It is in general the broad object of the present invention to provide ahinge mounting for a sash in a frame which is simple and rugged andrelatively inexpensive to manufacture.

A further object of the present invention is to provide a hinge whichcan be utilized for either of the right or left-hand side of a window.

The invention includes other objects and features of advantage, some ofwhich, together with the foregoing will appear hereinafter wherein thepresent preferred form of hinge of the present invention is disclosed.

In the drawings accompanying and forming a part hereof, Figure 1 is aperspective view showing the lower right-hand corner of a casement typesash installed in a suitable frame.

Figure 2 is a section taken through a typical casement type sashinstallation in a window frame.

Figure 3 is a plan view of a hinge of the present invention.

Figures 4 and 5 are respectively sections taken through the structuresshown in Figure 3 .along the lines 4-4 and 5-5 showing the shoeconstruction utilized.

Figure 6 is an end view of a hinge mountin showing the relation betweenseveral of its components in closed position.

The hinge of the present invention includes a first strap member I I, asecond strap member l2, athird strap member [3 and a shoe l4 slidablymounted upon the first strap member II.

The first strap member I I includes a first frame engaging portion It atone end thereof having a suitable aperture therein for insertion of ascrew 11 to attach the member to a frame 20. At its other end, the'firststrap member includes another frame engaging portion 18, this portionbeing relatively longer than the first frame engaging portion IE topermit of the hinge mount ing thereon by pin or rivet 19 of one end ofthe third strap member l3. The second frame en-- gaging portion [8 ofthe first strap member also includes several spaced apertures in whichscrews 2| can be inserted to attach the first member to the window frame20. Intermediate the frame engaging portions [6 and (8, the first strapmember includes a raised portion 22, this portion extending generallyparallel to the adjacent window frame and providing a track along whichshoe 15 can ride.

The second strap member I2 is hinged at one end by a pin or rivet 23 tothe slidable shoe M. The second strap .member also includes a pluralityof apertures 24 through which are inserted suitable wood screws or thelike to attach the second strap members to a rabbeted portion 26 on asash 21. The other end of the third lever I3 is hinged by a pin or rivet28 to the second strap member l2 intermediate the ends of the secondstrap member.

The second strap member is attached to the sash, the sash frame beingsuitably rabbeted to admit the strap member. In a casement type window,the top and bottom of the sash are rabbeted adjacent the inner corner ofthe sash as I have indicated at 26 in Figure 2, one of the hingedstructures of the present invention being mounted at the top and at thebottom of the sash and being attached to the top and bottom of theframe. This mounting permits the windows to be moved toward and awayfrom the frame to provide an opening of a desired extent or to entirelyclose the frame. The hinge mountings provided on the window areidentical and it is not necessary to distinguish between right andleft-hand hinges.

It will be observed, upon examining Figure 6, that the third member [3is secured to the second member I2 on the under side thereof and thatthe second member is hingedly mounted upon a raised portion providedupon the top of shoe M, as appears in Figure 4. This permits the thirdmember to move freely over the top of the first member ll so that thesecond member I2 can be positioned in a sash supporting position oneither side of the first strap member II. This permits the structure tobe utilized for installationupon either side of a sash, the structurethus serving as a mounting for a sash to swing outwardly and away fromthe first member in either a right hand direction or a left handdirection.

Another feature of the present invention is that the hinge mountingdescribed permits of adjustment of the tension placed upon the sash andthe degree of frictional control maintained on the Window so that itsopening and closing movement is opposed by a frictional force such thatslamming of the window can be avoided. This is effected by providing ahole 3| intermediate the ends of the raised portion 22 in the firststrap member and by providing a simple, tapered, conventional screw 32in this hole to extend, into engagement with the adjacent frame. Whenthe screw is driven into said frame with an ordinary screwdriver, theraised portion 22 bows and is drawn toward the sash frame. It is obviousthat the simple screw 32 could be replaced by any other suitable memberso long as it is adapted, when passed through said hole 3| and'engagedwith said sash frame 20, to draw the raised portion 22 toward the sashframe and hold it in any desired tensioned or bowed position. By flexingthe raised portion 22 on the first strap member from its normal positionparallel to the frame, one is able to provide a desired degree offriction between the shoes I4 and the raised portions 22. To this endand to permit the structure to be utilized for installation on eitherside of a window, shoe [4 is so fashioned that it will pass the element32. To effect this, the shoe is preferably made in the shape of a U, as,appears in Figure 4. However, a portion 33 of the U member is fashionedto fit the first strap member snugly, ends 34 being crimped over toengage portion 22 snugly with a sliding fit while the other portionc36of the U member is spaced above they portion 22, as will be apparentupon comparing Figures 4 and 5. The range of adjustment of strap II isthat permitted by the spacing between the bottom surfaces of crimpedends 34 of shoe M which rides along raised portion 22, and the adjacentsup.- porting surface of sash frame 20.
